Because there are three problems: 1, product design: the music controller can only be laid flat, and it will fall off as soon as it is erected. At the same time, the base must be placed in a fixed position. 2. Projection quality control: there is an electric door outside the polar meter RSpro lens, and the first opening opportunity is stuck in the middle. Listen to the customer service method and dial manually. I can barely dial it, but it feels tight. However, when the electric sliding door is closed, it gets stuck again and needs manual intervention. 3. Video technical problem: Connecting ps4 to start the game mode will make the screen unusable. Open HDMI2.0 to connect the Blu-ray player, and a green screen will appear on the screen. There are often splash screens and vertical bars when watching online movies.

—SUB525, a subwoofer jointly customized by Jimmy Technology and Harman Kardon, has a high positioning and is only suitable for Jimmy 1080P flagship projection H3S and 4K flagship RSPro2.
